采用茂锆硼酸盐络合物催化剂，在室温下实现了ε-己内酯（CL）、δ-戊内酯（VL）和1，3-二氧杂环庚烷-2-酮（6）的活性阳离子开环聚合。还成功地进行了CL与VL或与环状碳酸酯6的相应嵌段共聚。讨论了阳离子活性聚合的机理。
Living cationic ring-opening polymerization of e-caprolactone (CL), δ-valerolactone (VL) and 1,3-dioxepane-2-one (6) was achieved at room temperature by using zirconocene borate complex catalysts. Respective block copolymerization of CL with VL or with cyclic carbonate 6 was also successfully performed. The mechanism of the present cationic living polymerization is discussed.
